Remove every regular expression match from a string except for the first occurrence.
This is handy for removing or replacing matches in a string after the first one.
function removeDuplicateRegexMatchesExceptFirst (string, regex) {
var count = 0
var replaceWith = ''
return string.replace(regex, function (match) {
count++
if (count === 1) {
return match
} else {
return replaceWith
}
})
}
var string = 'Button__button___2a549 myprefix-action-button-component Button__action___3EoEX myprefix-button-component'
var regex = /myprefix-[a-zA-Z0-9-]*-component/gm
removeDuplicateRegexMatchesExceptFirst(string, regex)
// "Button__button___2a549 myprefix-action-button-component Button__action___3EoEX "Regex for the win!
